Tried cycling mixture, no effect - slightly lower rpms on lean. I recorded a short track to review, but guess what? in the track there was no shaking, no grinding metal, and steady(ish) needles for rpm/temps. mind you the track record is still not getting the engine right so I don't know.

Anyone else had this one? I think that's twice for me, the first time I thought I'd cooked the engine but now I'm pretty sure this is a bug.

The Merlin engine does fail in CoD if you maintain max boost and max revs for long enough and probably also if they are higher than recommended. I think its the Constant Speed unit that fails and that doesn't involve excessive engine temps. I don't know that its accurately modelled but its happened to me several time when I've been pushing too hard for too long.

OK, thank you. does this not register in the damage window though? governor failure or something? I held 3000 rpm for climb, and found that after I could still fly effectively, no loss of power, rpm control etc working fine just with the screen+needles shaking it was unplayable. I don't use the boost, as the throttle in spit 2a maxes out the manifold pressure at about 40% throttle currently, and the push lever stays where it starts locking max throttle at 100%

Also, no failure in the replay - but then replays are not working properly.

Is it just me being a newb then? what is the correct protocol for quick climb and boost control on the Spit2a? I've heard folks talking about the boost, but for me there is no difference between 40%-110% throttle other than manifold pressure going through the roof as far as I can tell, no extra rpms, no extra speed etc... :confused:

System.NullReferenceException: Object reference not set to an instance of an object.

plus a load of numbers and lettersafther this. i got one of these after each crash.

i looked up the meaning of this and from what i understood this error is when the code tries to use a setting that is set to 0 or "null" and cant handle it. so i decided to turn all of the video options in graphics settings on. just flew my first sortie that lasted over 20 mins (ran outa ammo with vulchers at manston). and second that was 40 mins, would have lasted longer but 109 got me over france. i have no idea if the log file error was to do with the graphics settings lol!

the settings i had to change were:

SSAO to ON
V Sync to ON
Grass to ON
shadows to ON

I have left anti aliasing off but all other settings are on (at least on low for each, some medium, but the above were the only ones i changed as they were off entirely)

my fps took a bit of a hit but its playable.

i think there is a problem with not having one of the above not turned on, at least for me. i will test each one tomorrow to see which was causing the problem for me.

I don't use the damage window but I just had a failure of a SpitII engine, it simply failed. I was down to 5 gallons and running low rpm/boost to stretch it out. After a while it begamn to misfire under low fuel pressure, causing intermittent vibration and eventually it stopped and wouldn't restart.

I don't know if this is what heppened to you? Failed fuel pressure?

The throttle currently controls boost levels over about 0-40% ov its range which is obviously a bug. I can get boost pressures between -4 and +6 but its hard to get exactly what I want and have to settle for about +/- 1lb.

Here are the boost figures from SpitIIa pilots notes for the Merlin XII and the Hurricane Merlin III (Spitfire will be the same). You'll find these splattered all over the forums.
